Subject [jira] [Commented] (HADOOP-8251) SecurityUtil.fetchServiceTicket broken after HADOOP-6941
Date Fri, 06 Apr 2012 05:01:19 GMT

Todd Lipcon commented on HADOOP-8251:
-------------------------------------

Hey Devaraj. Sorry, I already committed this, and I don't feel comfortable changing the code
if I can't test it (I don't have ready access to an IBM JDK installation). I think rather
than just fixing this bug, someone should run through the whole security test plan on the
IBM JDK -- perhaps as part of HADOOP-7211?

bq. Seems like the methods are there and with the desired signatures..
bq. Did I miss something?

I was basing it on these docs:
http://www.ibm.com/developerworks/java/jdk/security/60/secguides/jgssDocs/api/index.html?com/ibm/security/jgss/mech/krb5/Krb5RealmUtil.html
which don't mention krb5util in that package

> HADOOP-6941 replaced direct references to some classes with reflective access so as to
support other JDKs. Unfortunately there was a mistake in the name of the Krb5Util class, which
broke fetchServiceTicket. This manifests itself as the inability to run checkpoints or other
krb5-SSL HTTP-based transfers:
> java.lang.ClassNotFoundException: sun.security.jgss.krb5
